| * Size cap for local files Desktop loads as data URLs (composer attach, image | |
| * preview, …). | |

| * Main owns the persisted value; the renderer mirrors it in Settings → Chat and | |
| * clamps optimistically before sending. Both ends have to agree on the default | |
| * and the bounds, so they live here rather than as two constants with a | |
| * "keep these in sync" comment between them. | |
| * | |
| * The whole file is base64-buffered in main, so this is a memory guard, not a | |
| * model limit. The ceiling is only a typo guard — values well below it can | |
| * still OOM the app. | |
